The latter are circular or rectangular vessels, holding from 500 to 1500 gallons each, according to the capacity of the factory, and fitted with steam coils at the bottom and skimming troughs at the top. In them the syrup is quickly brought up to the boil and skimmed for about five minutes, when it is run off to the service tanks of the vacuum pans.
By fractional distillation is meant the separation of a mixture having components which boil at neighbouring temperatures.
Ortho-nitrophenol, C6H4.OH N02(1-2), crystallizes in yellow needles which melt at 45° C. and boil at 214°C. Para-nitrophenol, C6H4.
Soon after the Christian era central Asia began to boil over, and at least seven great.
Formerly the pans were heated by open firing from below; but now the almost universal practice is to boil by steam injected from perforated pipes coiled within the pan, such injection favouring the uniform heating of the mass and causing an agitation favourable to the ultimate mixture and saponification of the materials.
The ordinary method of adding resin consists in stirring it in small fragments into the fatty soap in the stage of clear-boiling; but a better result is obtained by separately preparing a fatty soap and the resin soap, and combining the two in the pan after the underlye has been salted out and removed from the fatty soap. The compound then receives its strengthening boil, after which it is fitted by boiling with added water or weak lye, continuing the boil till by examination of a sample the proper consistency has been reached.
It forms silky crystals which melt at 6° C., and boil at about 144° C. with decomposition.
It crystallizes in needles which melt at 173-174° and boil at 349-350° C., and are volatile in steam.
Sometimes it is necessary to allow the solution to stand for a considerable time either in the warm or cold or in the light or dark; to work with cold solutions and then boil; or to use boiling solutions of both the substance and reagent.
In general, isomers boil at about the same temperature, as is shown by the isomeric esters CH1802: Methyl octoate..
Fora similar reason secondary alcohols boil at a lower temperature than the corresponding primary, the difference being about 19°.
A similar depression is presented by methyl alcohol (67°) and methyl ether (-23 °) Among the aromatic di-substitution derivatives the ortho compounds have the highest boiling-point, and the meta boil at a higher, or about the same temperature as the para compounds.
Of the tri-derivatives the symmetrical compounds boil at the lowest temperature, the asymmetric next, and the vicinal at the highest.
It forms rhombic prisms or plates which melt at 25° and boil at 83°, and has a spiritous smell, resembling that of camphor.
It crystallizes in octahedra which melt at 120.5° C. and boil at 290° C. Its vapour burns with a red flame.
European children born in the country are apt to be seriously disfigured, as in their case the boils almost invariably appear on the face, and whereas native children have as a rule but one boil, those born of European parents will have several.
It crystallizes in prisms, which are soluble in water, melt at 16° C., and boil at 160 5° C. When fused with an alkali, it forms propionic acid; with bromine it yields aß-dibromisobutyric acid.
To boil off say 300 lb of thrown silk, about 60 lb of fine white soap is shred, and dissolved in about 200 gallons of pure water.
They are mostly colourless liquids which boil without decomposition, or solids of low melting point.
In the one case they are entirely restricted to the neighbourhood of the boil or ulcer, whereas in the other there is a general infection of the body, the organisms spreading to all parts and being met with in the spleen, liver, bone-marrow, &c., and (rarely) in the peripheral circulation.
The fundamental idea of Soxhlet's method for sterilizing milk is to boil it for forty minutes in small bottles holding just enough for one meal, and closing the same with an impervious stopper, which is only removed just before use.
After this treatment, the mixture is run into lead-lined vats and treated with sulphuric acid, steam is blown through the mixture in order to bring it to the boil, and the anthracene is rapidly oxidized to anthraquinone.
Before discussing the methods now used in detail, a summary of the conclusions reached by Victor Meyer in his classical investigations in this field as to the applicability of the different methods will be given: (I) For substances which do not boil higher than 260° and have vapours stable for 30° above the boiling-point and which do not react on mercury, use Victor Meyer's "mercury expulsion method."
It crystallizes in large plates, which melt at 98.5° C. and boil at 390° C. It is readily soluble in warm ether and in hot glacial acetic acid.
It crystallizes in white plates, which melt at 45° C. and boil at 302° C. It is almost insoluble in water, but readily volatilizes in steam.
Orthophenylene diamine, C 6 H 4 (NH2)2, crystallizes from water in plates, which melt at 102 -103° C. and boil at 256-258° C. When heated with io% hydrochloric acid to 180° C. it yields pyrocatechin (Jacob Meyer, Ber., 1897, 30, p. 2569).
